Cloud Service Security Profiles for Breach Isolation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In cloud computing environments, devices with multiple cloud client applications are vulnerable to security breaches if compromised, as they rely on stored authentication tokens, leading to potential unauthorized access across all cloud services on the device.
Innovation Solution
A method and system that detect potential security breaches on user devices, send breach notifications to corresponding service providers, and restrict access until a security challenge is completed, enhancing security profiles across connected devices and shared user accounts.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If cloud client applications rely on stored authentication tokens for continuous access, then ease of operation is improved, but security is worsened as all applications become vulnerable if the device is compromised
Solution Approach 1:
The patent segments the authentication system by introducing separate security profiles for each cloud service application. Instead of a single device-level authentication token, each application has its own security profile with independent credentials and authentication mechanisms, isolating security breaches to individual applications rather than compromising all services on the device
Solution Approach 2:
The patent introduces security profiles as an intermediary layer between the device and cloud services. These profiles contain service-specific authentication credentials and security policies that mediate access requests, allowing continuous operation while maintaining service-level security control independent of device compromise
2Reliability
If security profiles are enforced with challenges for each access, then security is improved, but ease of operation deteriorates due to repeated authentication requirements
Solution Approach 1:
The patent implements dynamic security profiles that adjust authentication requirements based on risk assessment. Security challenges are enforced selectively rather than uniformly - the system dynamically determines when full authentication is needed versus when trusted access can continue, balancing security verification with operational convenience
3Adaptability or versatility
If multiple cloud client applications are installed on a single device, then adaptability is improved, but security vulnerability increases as a single compromise affects all services
Solution Approach 1:
The patent segments security management by creating independent security profiles for each cloud service application. Each profile contains service-specific credentials, authentication methods, and security policies, ensuring that a compromise in one application does not automatically compromise other services on the same device
Solution Approach 2:
The patent applies local quality by customizing security measures for each specific cloud service rather than using a uniform security approach. Each security profile is tailored to the specific requirements and risk profile of its associated service, allowing appropriate security control at the application level while maintaining multi-service adaptability

AI summary
A system includes: a CPU, a computer readable memory and a computer readable storage medium associated with a computer device of a service provider; program instructions to receive, by the computer device, a breach notification from a user device, wherein the user device includes a client that corresponds to the service provider, and the breach notification indicates a potential security compromise of the user device; program instructions to identify, by the computer device, a plurality of user devices that have the client; and program instructions to transmit, by the computer device, a respective security profile to each of the identified plurality of user devices, wherein each of the respective security profiles defines a security challenge that must be completed to obtain access. The program instructions are stored on the computer readable storage medium for execution by the CPU via the computer memory.
